# If the CATALINA_HOME enviroment variable is not set on your system you have

# to adjust this path to point to the lib directory of your Tomcat installation
# (if you installed the Tomcat using the package manager of your distribution
# this is usally /usr/share/tomcat6/lib)
# To set an environment variable you have usally to add an file to the /etc/profile.d

# using the 'export' command. This line might look like this:
# export CATALINA_HOME=/usr/share/tomcat6/lib
